 name of Dittany, of Crete.) Mcench. ex Benth. lab. p. 333. 

 Origanum, spec, of Lin. and other authors. 



LIN. SYST. Didynamia, Gymnospermia. Calyx ovate-campanu- 

 late, 13-nerved at the base ; upper lip elongated, entire, erect; 

 lower lip truncate, almost wanting, or very shortly bidentate ; 

 throat naked inside. Tube of corolla exserted from the calyx, 

 equalling the imbricate bracteas ; limb bilabiate ; the upper lip 

 erect, emarginate, flatfish : the lower lip spreading, trifid, with 

 nearly equal, entire lobes. Stamens 4, erect, ascending, scarcely 

 distant, exserted, didynamous : lower ones the longest ; filaments 

 glabrous ; anthers 2-celled : cells distinct, diverging, or divari- 

 cate. Upper lobe of style short ; stigmas minute. Shrubs with 

 quite entire leaves. Flowers aggregate into oblong spikelets. 

 Bracteas orbicular, membranous, coloured, loosely-imbricate, 

 much longer than the calyxes, equalling the tubes of the corollas. 

 This genus differs from Origanum, from which it has been sepa- 

 rated, in habit, calyx, corolla, &c.

2 A. TOURNEFORTII (Benth. lab. p. 333.) leaves sessile, orbi- 

 cular, sub-cordate at the base, and are, as well as the branches, 

 quite glabrous or ciliated. tj . F. Native of the Grecian Ar-

 the spikes being more dense ; in the bracteas being broader, and 

 the genitals a little shorter. Lower lip of calyx distinctly biden- 

 tate. Corollas purple, furnished with a small obtuse spur under 

 the throat. Habit of Rhodlola rbsea.

Cult. The species of this genus are liable to be killed by 

 severe frosts if allowed to remain in the open air ; but in com- 

 mon winters, if planted against a south wall in a dry soil, will 

 survive. It is, however, proper to keep a few reserve plants in 

 pots, that they may be protected by placing them in a green- 

 house or frame. A rich light soil suits them best ; and cuttings 

 are readily rooted under a hand-glass.
